The notmuch email frontend have a problem parsing email headers.
The problem is headers like this
From: "=?iso-8859-1?q?=D8yvind_Normann?=" <oyvind.norman@uio.no>
which my mailbox got a lot of. The frontend show the address as
=?iso-8859-1?q?=D8yvind_Normann?=
instead of
Øyvind Normann
The problem is the quotes around the MIME encoded string. Mutt and
Gnus handle these headers properly, but notmuch do not.
Any hope of having this fixed in a future version of ntomuch?

http://tools.ietf.org/html/rfc2047#page-8
states quite clearly:
+ An 'encoded-word' MUST NOT appear within a 'quoted-string'.
I'd argue that notmuch is doing the right thing here, and that MUAs that
wrap encoded words in quotes (or that apply decoding rules within quoted
strings) are the ones that need fixing.

Well, feel free to spend time on trying to get the other mail programs
changed. I do not have the privilege to give that project a priority
myself.
I just hope the notmuch developers can choose to follow the robustness
principle[1] in this case, and be liberal in what notmuch accept, and
conservative in what notmuch send. After all, gnus, mutt and pine
handle these from fields.

It's a nice stick to beat people with, but I'm not sure it's directly
applicable here. Notmuch is accepting the input, it just isn't
displaying it the way you want. I guess if somebody has some patches for
"sloppy header parsing", we can weigh the pros and cons then.
If someone wants to follow up on this, we are currently using
http://spruce.sourceforge.net/gmime/doc/gmime-gmime-utils.html#g-mime-utils-header-decode-text
There is some discussion there about dealing with bad inputs; I don't
know if it is directly relevant.

Based on
http://comments.gmane.org/gmane.mail.mime.gmime.devel/65
I thought gmime was supposed to be dealing with broken RFC 2047
encoding now. Am I misinterpreting it? Maybe a bug needs to be filed
against gmime?

Well, I guess that is mostly a question of semantics and definitions.
To me it isn't really accepting the input when I try to reply to an
email with the problem in question and end up with

One thing is not seeing the name properly in my client, but
broadcasting to my contacts my tools inability to process the From:

solved. I hope Austin is right that this bug is fixed in later
versions of gmime. I will try to upgrade and see if it solve the
issue.
